This is a nice little piece with tan rhombohedral Ankerite crystals to 7mm set on clear Quartz crystal points. 

This specimen comes with a label from the Abe Rosenzweig Collection, a well known collector, dealer, and teacher and the Oberlin, Ohio address dates it between 1970 and 1977, so it's more vintage than antique.
